The type-c interface is generic, but can actually be categorized into many different types depending on the purpose and the protocols supported.
According to different functions, it can be divided into:
Type-C charging cable: only supports charging function;
Type-C data cable: supports charging + data transfer function;
Full-function Type-C data cable: support fast charging + data transmission + video transmission function;
According to the function selection, we also need to pay attention to the supported charging power/protocol, interface transmission standard and so on.
PD fast charging data cable: (current size classification)
According to the current size can be divided into: 2A, 3A, 5A, 6A and so on.
The higher the current, the more expensive it is, and the high-current version can be downward compatible with the small-current version of the device.
3A fast charging, working power has 18W/27W, 33W.
5A fast charging, working power has 22.5W/40W, 55W.
6A fast charging with operating power of 30W/65W, 120W.
The USB-C Gen2 version of the full-featured dual Type-c cable not only supports PD100W fast charging, but also supports 10gb/s data transfer for 4K HD screen casting.
